This tutorial explains how magnetic resonance imaging (MRI) systems use the reaction of hydrogen atoms moving in a magnetic field to yield a detailed medical image. The types of magnetic fields ...

Resonance in chemistry is a tool used (predominately in organic chemistry) to represent certain types of molecular structures. Resonance is a key component of valence bond theory and arises when no ...

Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

Meet Steven Turner, curator at the Smithsonian's National Museum of American History, as he discusses the Smithsonian's scientific instrument collection. This video focuses on instruments that ...

Surface plasmon resonance (SPR) is a real-time, label-free optical technique used to detect and quantify molecular interactions. SPR has important applications in drug discovery and development and ...

It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...
